[ARM] 5536/1: Move clk_add_alias() to arch/arm/common/clkdev.c
This can be used for other arm platforms too as discussed on the linux-arm-kernel list. Also check the return value with IS_ERR and return PTR_ERR as suggested by Russell King. Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
